2) As the block slides down, its potential energy converts into kinetic energy. If its initial velocity is 1.2 m/s (at x = 3 m), determine its velocity, v, at x = 0.8 m. Your answer must include 2 places after the decimal point and the proper unit. Take g = 9.81 m/s2. v = 1 m/s y = 0.25x? k = 5 kN/m buwiel X 3 m
3. For this series of 5 questions, a block is released from the position shown with a certain initial velocity. It then slides down the smooth (friction-less) path for which the function is given in the image. You will be asked to solve for different things. Please pay attention: the numbers may change from problem to problem since they are randomized. 2) As the block slides down, its potential energy converts into kinetic energy. If its initial velocity is 1.5...
5) If the block has mass of 40 kg and its initial velocity is 3.4 m/s (at x = 3 m), determine the maximum compression of the spring (after the block has pushed in the spring and come to a stop). The spring constant is given in the image. Your answer must include 3 places after the decimal point and the proper unit. Take g = 9.81 m/s2. v = 1 m/s y = 0.25x k = 5 kN/m www.nl...
4) If the block has mass of 70 kg and its initial velocity is 3.4 m/s (at x = 3 m), determine the normal force N which the path exerts on the block right before it reaches the spring (at x = 0).

As the block slides across the floor, what happens to its kinetic energy K, potential energy U, and total mechanical energy E?
A block has an initial kinetic energy K. If the block moves in the opposite direction with one fifth its initial speed, then what is its new kinetic energy? 4/5 K K/25 -K/5 -K/25 None of the above. A block (6 kg) starts from rest and slides down a frictionless ramp #1 of height 9 m. The block then slides a horizontal distance of 1 m on a rough surface with kinetic coefficient of friction u 0,5. Next. it slides...

15-2. A 20-15 block slides down a 30° inclined plane with an initial velocity of 2 ft/s. Determine the velocity of the block in 3 s if the coefficient of kinetic friction between the block and the plane is uk = 0.25.
A block (6 kg) starts from rest and slides down a frictionless ramp #1 of height 6 m. The block then slides a horizontal distance of 1 m on a rough surface with kinetic coefficient of friction μk = 0.5. Next, it slides back up another frictionless ramp #2. Find the following numerical energy values: 1.Initial gravitational potential energy on Ramp #1: U1G = J 2.Kinetic energy at bottom of Ramp #1 before traveling across the rough surface: K =...
